Polyester fibers are compressed and finishes are applied according to the process or application they are used for.
All of the excellent characteristics of polyester apply to polyester felt, including good resistance to chemicals, abrasion
and dry heat degradation, plus excellent dimensional stability. Polyester felt is most commonly used in dust collection
processes, where the air flow is either forward or reverse pulse. The direction of the air flow dictates the finish required.
